This study investigated the potential pollinators, floral visitors and predators of the Leucaena leucocephala. Monitoring of the standardized number of flowers was done at specified time interval, and the number of predators was also counted at standardized time interval and the data collected were analyzed and tested using F-test. There was a positive relationship on the floral visitors and individual probing flowers ( P<0.05) however the difference between visitation and probing rate was insignificant ( P>0.05). The predation had positive correlation with probing while having negative relation with visitation. The relationship between the visitation and probing suggests that, there is a need to conserve the pollinators in integrated approach by considering other species. This will benefit not only Leucaena leucocephala but also other plant species in the restored sites. Further studies should be done to determine the impact of predators other than dragonflies on the pollination and seed setting.
